Description

BACKGROUND OF THE INVENTION The present invention relates to swinging sliding door vehicles, mainly passenger vehicles, with one or two closed doors in the vehicle wall and open doors in front of the vehicle wall which are guided by guide rails and a telescopically foldable guide the actuator has swing arms for swinging the door wings from the closed position to the open position, and the actuator exerts a reaction force on the swing arms which locks the swing arms in the closed position.

ADE-OS3 630 229 A swinging sliding door of the type described in the preamble is known in which the door leaves are moved by a pneumatic cylinder while locking in the locking position. The locking is effected by the action of the cylinder foot on an angle lever which turns the door leaf in and out through a swinging arm associated with a guide track and locks it in the locked position. From the nail lift, a switch bar is led to the opposite side of the door, where a suitable lever system controls the other side of the door. If compressed air is missed, the door will remain locked. Therefore, an auxiliary emergency lever must be fitted which releases the locking mechanism mechanically.

Passenger vehicles are very often fitted and constructed in such a way that all their controls and auxiliaries are powered by electricity only.

It is therefore an object of the present invention to modify the pneumatically operated sliding sliding door so that it can be moved and locked by an extremely simple electric drive.

It is a further object of the present invention to provide, by means of minimal means, an emergency trip that is triggered in the event of a power failure.

SUMMARY OF THE INVENTION According to the present invention, the actuator is configured as an electric motor drive unit mounted on the side above the door opening, the drive disk of which is actuated by one or two door numbers through a traction sheave driven by a turning disc and has a pivotable rim. it has an eccentric control pin which is connected to a control arm mounted on the door post, and the door post has roller arms which are guided in the guide rails on the side of the door; and cannot be opened manually or by wind.

Further details of the invention will be described with reference to the accompanying drawings in connection with an exemplary embodiment.

Figure 1 is a plan view of the actuation system of a two-leaf swinging sliding door in the closed position, Figure 2 shows the same arrangement but in the open position, Figure 3 is a short vertical sectional view of the door complete with a view of the gear motor in the roof area; Figure 5 is a sectional view of the motor drive assembly, Figure 5 illustrates the kinematics of a swinging sliding door according to the invention when the right door leaf is unfolded and locked, and Figure 6 shows an internal view of the left door hitch mechanism.

As shown in Figure 1, there is a left-hand door leaf 3 and a right-hand door number (4) between the left-hand door frame (1) and the right-hand door frame (2). A telescopic rail (5) is located just behind the door leaves (3,4). This telescopic rail (5) is suspended from the pivot arms (6,7), which are connected via the pins (8,9) to the door bracket in the roof area.

Directly adjacent to the door frames (1, 2) are door posts (10, 11) carrying roller arms (12, 13). Also on the door posts (10, 11) are the control levers (14, 15) provided with a gap, to which the control pins (16, 17) are connected. These control pins (16, 17) are mounted on pivotally mounted flanges (18, 19) which also carry ball heads (20, 21). The two ball heads (20, 21) are connected to one another via an adjustable link rod (22). Rotating the flange (19) at a limited angle counterclockwise loses the flange (18). As a result, the control arms (14, 15), the door posts (10,11) and the roller control arms (12, 13) also rotate in opposite directions, whereby the door wings (3, 4) and the telescopic rail (5) connected thereto 2, they move out of the plane of the body.

After this rotation process, the door leaves (3,4) can be shifted in the opening direction until the state of full opening shown in Figure 2 is reached. The actual opening and closing movement is effected by a dash (23), indicated by a dotted line, which is guided by a driven disc (24) and a turning disc (25).

The flange (18) and the pivoting disc (25) move about the same axis of rotation (26) but are not interconnected. The same applies to the flange (19) and the driven disc (24) and the axis of rotation (27). The traction sheave (23), preferably a non-slip toothed belt, is fixedly connected to the door apertures (3, 4) through the obliquely adjustable pull arms (28, 29), while the two pull arms (28,29) cross in space. When the driven dial (24) and the rotary dial (25) are rotated clockwise, the lever (23) moves in the direction of the arrows (30), so that each door (3,4) opens.

A comparison of Figures 1 and 2 shows that the pull arms (28, 29) not only move laterally along the ideal line, but also turn outward with a door leaf thickness. Meanwhile, the towing member (23) is subjected to some degree of deformation and elongation as soon as

This is particularly noticeable for the clamping device (31) in Figure 1 and the clamping device (32) in Figure 2. Preferably, the pull levers (28, 29) are configured such that each of the clamping devices (31, 32) has the same distance to the right and left of the door symmetry plane. Thereby, and by using a rotating disc (25) substantially smaller than the driven disc (24), the elongation of the drawbar (23) can be minimized.

The rotation and displacement operations described so far are provided by a single actuator whose core is an electric motor indicated by a dotted line (33) to which a worm gear is connected. The driven shaft of the gear unit coincides with the axis of rotation (27). The housing of the motor drive unit is rigidly connected to the flange (19) so that it can also be rotated in a limited manner around the axis of rotation (27). When the electric motor (33), preferably an electronically controlled DC motor, is energized, a certain torque is generated on its driven disk, which must operate clockwise from the closing position shown in Fig. 1. At the same time, however, the gear housing and thus the flange (19) are subjected to a counter-torque of the same magnitude, which attempts to move the flange (19) and thus the flange (18) counterclockwise. As long as the door leaves (3, 4) are not turned, no translational (linear progressive) motion can occur. Consequently, the counter-torque must first rotate the electric motor (33) about 45 ° to the left. Meanwhile, the control pin (17) also pushes the control lever (15) to the left and the crank (13) tilts to the right.

The same processes occur with the opposite sign on the left door frame (1), so that the door wings (3,4) and the telescopic rail (5) can turn outwards.

Fig. 3 is an exploded vertical sectional view of a swinging sliding door according to the invention, complete with a view of the electric motor (33) and its coupling, with a driven disc (24), a spherical head (21) and a gear lever (15).

The door number (4) having a built-in window (4a) is shown in section. The door post (11) is embedded in the floor or roof area and, in addition to said control lever (15), carries the upper roller arm (13) and a lower roller arm (34). The guide rails (35,36) for the roller swivel arms (13, 3 4) are integrated in the grooves of the doorway (4).

Figure 4 is a sectional view of the motor drive unit. On the left-hand side of the figure, the door pillar (11) with the roller pivot (13) and the elbows (15) is shown. The electric motor (33) rotates a driven shaft (38) through a worm gear (37) which is connected to the tilted disc (24). The motor drive unit is pivotally suspended on a base plate (39). An electromagnetic coupling (40) is disposed between the driven shaft (38) and the driven disk (24), so that the driven disk (24) can only transmit torque when the electromagnetic coupling (40) is in the excited state.

The ball head (21) is mounted on the flange (19), which allows the rotation of the motor drive unit to be transmitted to the other door side. In addition, a pin (42) is fastened to a bracket (41) extending from the engine drive unit, which is capable of receiving, via transverse bores (42a, 42b), the wires for emergency release.

Figure 5 is a top view of the right door control elements. The position of the components in a closed door is indicated by a solid line, while the dotted lines indicate their open position. The figure clearly shows that the control chamber (15) has a curved control slot (15a). In the closed position, the control pin (17) rests on a portion of the control path which forms a right angle to the axis of rotation (27). This means that a clockwise torque exerted by the door pillar (11) cannot exert a tangential (tangential) force on the flange (19). In other words, the clamping lever (15) occupies a true deadlock position which cannot be eliminated by pulling or pulling the door leaf (4). The door is thus securely locked. This condition is further facilitated by a screw spring (42). To start the opening, the electric motor (33) must be switched on in the opening direction. Simultaneously activate the electromagnetic clutch (40). However, since the driven pulley (24) cannot move due to the locking of the door leaf (4), the counter-torque is transmitted to the motor drive unit. This rotates counterclockwise, while the control lever (15) is moved into position (15 *). The door pillar (11) rotates clockwise and moves the roller lever (13) to position (13 '). Meanwhile, the door leaf (4) turns in front of the body plane. By turning the door, it is now possible to move the door parallel to the body plane of the door by means of the driven disk (24) by means of the pulling member (23).

The left door leaf (3) is unlocked and moved through the connecting rod (22) in a similar manner as shown in Figure 6. There, a base plate (43) is integrated in the roof region which carries both the bearing (44) of the door column (10) and a bearing shield (45) for the pivoting flange (18) and the pivoting disc (25). The control pin (16) and a pin (46), on which a screw spring (47) is engaged, are mounted on the flange (18). The diameter of the turning disk (25) is substantially smaller than that of the driven disk (24).

In order to transfer the forces non-slip, it is preferable to use a toothed belt as a traction device, provided that the driven disc (24) and the rotating disc (25) are provided with appropriate teeth. This enables the two door panels (3, 4) to move in synchrony even after extended operation.

The emergency opening of the door shall be provided even if the electric motor fails or the power is cut off. Before the door can be pushed by hand, it must first be unlocked. This is done by an inner hub with an external bowden wire which rotates the flange (19) with the motor drive unit to the left while moving the control lever (s) (14) out of its dead center position. Egy3

At the same time, the roller arms (12, 13) push the door leaf (3, 4) out of the plane of the door, so that the door leaf (3, 4) can be moved manually.

Since the electromagnetic clutch (40) is disconnected when the power is off, the driven disc (24) runs easily and freely. When opening or closing the door manually, it is sufficient to push one of the door latches (3, 4). Because you drive the other one! the timing belt.

If a slow-rotating, high-torque electric motor is used, the self-locking worm gear and the electromagnetic clutch may be omitted.

The coupling may also be missing in the case of an electric motor equipped with a bevel gear

The swinging sliding door according to the invention can be advantageously applied to all rail and road vehicles. A single electric motor, powered by a DC power supply available for control purposes, is sufficient to operate any single or double swinging sliding door. This engine is both surprisingly simple to move and lock the door.
